You are right. There is no locking nut, just replaceable tappets.
Tappets (item #5 in diagram) are selected from a range of thicknesses and installed to provide proper valve clearance. It is not expected to ever need service, but in case of overhaul the service manual describes a procedure for measuring and calculating valve tappet size for proper clearance.
You can download a copy of the service manual and review the procedure for yourself any time you like! Look for the procedure in section 11B.
